Saving The Planet Begins With Saving The Coral Reefs, Marla Maconochie
Saving The Planet Begins With Saving The Coral Reefs, Marla Maconochie
Honors Projects
This honors project uses a children’s book format to aid in explaining the importance of saving the coral reefs. This book will be informing the younger generations about important, yet complicated issues at hand in a way that they can understand and relate to. The book explains how coral reefs are important for oxygen production, biodiversity, research opportunities, protection of coastal environments and for the economy. The children’s book explains how human activities and natural stressors can impact coral survivorship. The book explains how overfishing allows for excessive algal growth that smothers corals and tackles how coral bleaching occurs and …
Coral Species Distribution And Percent Cover Of Sessile Organisms On Protected And Non-Protected Coral Reefs In Digir, Buga, Dubbir, And Kanir Kinnidup, Guna Yala, Panama, Sarah Paulson
Independent Study Project (ISP) Collection
Coral reefs are the most productive, biodiverse ecosystems in the ocean despite covering only <.5% of the ocean floor. In today’s changing climate, coral reefs face a multitude of threats including ocean warming, coral bleaching, ocean acidification, overfishing, increasing human population, and coral mining, among others. One way to protect coral reefs is to establish a marine protected area to limit damage and contamination. This study aimed to examine coral species distribution as well as percent cover of sessile organisms and substrates including coral, fire coral, algae, and sponges on protected and non-protected reefs in order to attempt to analyze the effect of protection on coral reefs in Guna Yala, Panama. Based on the data collected, protected areas had higher algae cover (P<.01, df=107), lower coral cover (P<.0001, df=138), and a higher relative abundance of corals with a “weedy” life history such as Porites astreoides (P<.05, df=80). The data also showed that uninhabited islands tended to have significantly higher average coral cover (P<.0001, df=146) and lower average algae cover (P<.0001, df=161), as well as lower relative abundance of P. astreoides (P<.01, df=134). When the protected site sampled was compared to an unprotected site that was around the same island, the protected area was found to have higher coral cover (P<.01, df=71) and lower algae cover (P<.05, df=72) than the unprotected area. Ultimately, lack of human population and protected status were found to be positive factors for coral reef health, and future study should be done to further examine the relationship between these two factors.
Prey Naïveté And Predator-Prey Interactions Between Pterois Volitans, Pomacentridae, And Tetraodontidae In Two Reefs In The Guna Yala Archipelago, Panama, Jesse Garrett-Larsen
Prey Naïveté And Predator-Prey Interactions Between Pterois Volitans, Pomacentridae, And Tetraodontidae In Two Reefs In The Guna Yala Archipelago, Panama, Jesse Garrett-Larsen
Independent Study Project (ISP) Collection
The invasion of Pterois volitans along the Atlantic coast of the Americas is one of the top marine conservation issues of the century. Prey naïveté has been suggested as a mechanism for the success of P. volitans, but conclusive field observations have not been completed. This study tested for prey naïveté in situ by comparing time spent by Pomacentridae and Tetraodontidae in close proximity to P. volitans and a native predator, Cephalopholis cruentata. Difference in time spent by Pomacentridae and Tetraodontidae in the presence of the two predators was observed. The predators P. volitans and C. cruentata were sequentially observed …
Integration Of Biological Effects, Fish Histopathology And Contaminant Measurements For The Assessment Of Fish Health: A Pilot Application In Irish Marine Waters, Michelle Giltrap, Jenny Ronan, John Bignell, Brett Lyons, Evelyn Collins, Heather Rochford, Brendan Mchugh, Evin Mcgovern, Lorraine Bull, James Wilson

Articles
This study investigates the use of a weight of evidence (WOE) approach to evaluate fish health status and biological effects (BEs) of contaminants for assessment of ecosystem health and discusses its potential application in support of the Marine Strategy Framework Directive (MSFD). External fish disease, liver histopathology and several BEs of contaminant exposure including 7-ethoxy resorufin O-de-ethylase (EROD), acetylcholinesterase (AChE), bile metabolites, vitellogenin (VTG) and alkali labile phosphates (ALP) were measured in two flatfish species from four locations in Ireland. Contaminant levels in fish were generally low with PCBs in fish liver below OSPAR environmental assessment criteria (EAC). There were …
A Multibiomarker Analysis Of Pollutant Effects On Atlantic Stingray Populations In Florida’S St. Johns River, John Whalen
A Multibiomarker Analysis Of Pollutant Effects On Atlantic Stingray Populations In Florida’S St. Johns River, John Whalen
UNF Graduate Theses and Dissertations
The goal of this study was to examine the potential health effects of organochlorine (OC) and polycyclic aromatic hydrocarbon (PAH) exposure on Atlantic stingray populations in Florida’s St. Johns River (SJR). Special emphasis was placed on identifying OC- and/or PAH-related effects in stingrays from areas of the lower (LSJR) and middle (MSJR) basins shown to possess elevated levels of these compounds, as well as characterizing baseline levels of pollutant exposure in the SJR shipping channel, which may be subjected to dredging in the near future, potentially resuspending and redistributing contaminated sediments and increasing pollutant-associated effects. To accomplish this, we measured …
Dredging Land Reclamation Causing Mucus Development In Massive Spherical Corals In The Spratly Islands, South China Sea: The Effects On China’S Fishing Industry, Tiffany K. Ho
Undergraduate Research Posters
Images from Asia Maritime Transparency Initiative depicted huge masses of white coral mucus secreted from coral reefs in the Spratly Islands of the South China Sea, an area where several land reclamation projects are occurring. The purpose of this research was to understand how increased sedimentation levels from the dredging land reclamation method affects mucus development in massive corals, such as Acropora, located in these reefs. Journal articles that focused on the biology of coral mucus, bacterial communities associated with coral tissue, mucus, and seawater, coral mortality from different environment impacts, coral coverage of reefs in Spratly Islands, and symbiotic …
